For very short pulse duration of the thruster firing, the specific impulse is degraded by __________

For very short pulse duration of the thruster firing, the specific impulse is degraded by __________ Correct Answer 5-25%

The specific impulse degradation can be from 5% to 25%. This is because the performance during thrust build up and thrust decay are inferior compared to that at the rated operating conditions (without any transience).
